I-LEFOO LFM208 inzwa yengcindezi eseleyo ingumkhiqizo ophakeme kakhulu owenziwe ngokukhethekile ukulawulwa kwengcindezi yokulawula intuthu amasistimu ezakhiweni eziphakeme. Into yokulinganisa ingcindezi eyinhloko yamukela i-chip yengcindezi ye-US SM. Ngemuva kwe-zero, isilinganiso esigcwele nesinxephezelo sokushisa, inzwa yengcindezi esele inokunemba okuphezulu nokuzinza okuhle ukuhlangabezana ngokuphelele kwezidingo zokulawulwa kwengcindezi zohlelo lwengcindezi, umkhiqizo uqobo onenkomba yesimo esiluhlaza kanye nenkomba ye-alamu yengcindezi ebomvu. Umkhiqizo wamukela amandla angama-24 V DC wokuphakela amandla okuphepha okukhethekile kwamandla aphansi: usebenzisa indlela yokuzikhethela yamabhasi amabili noma indlela yokuxhumana engama-485, izintambo ezilula, zokonga ubukhulu bomkhiqizo yi-86 * 86 * 38. Lo mkhiqizo ikakhulukazi wenzelwe igumbi langaphambili lekheshi lomoya lokuhlinzeka ingcindezi kanye nezitebhisi ezikhethekile, Ingcindezi yomkhiqizo kanye nefektri yengcindezi yokusetha kabusha ibibekiwe phambilini, isiza asidingi ukusetha isiza, ngcono kakhulu ukunemba kokulawula komkhiqizo, Ngenkathi kunciphisa kakhulu umsebenzi wokwakha wesiza usetshenziselwa ikakhulu egumbini langaphambili lekheshi, igumbi langaphambili elabiwe, isiphephelo esivaliwe, izitebhisi, isitebhisi sokuhlukanisa isilinganiso sokulinganisa nokulawula; Ingasetshenziselwa ukutholwa kwengcindezi yasendlini nangaphandle Kwakungasetshenziswa futhi kusilinganiso sokucindezela nohlelo lokulawula lomile igesi efana nohlelo lokuqapha izihlungi.
Izici:
* Thola izingxenye zenzwa ye-MEMS engenisiwe
* Sekela amabhokisi angama-86 afakiwe
* Izinhlobo ezimbili zezindlela zokuxhumana zingakhethwa
* Uhlangabezane ngokuphelele izinga likazwelonke "Isicelo Sezobuchwepheshe Sokwakha Uhlelo Lokuvimbela Intuthu Nokukhipha"
* Ukuqashwa kwengcindezi kwamakamelo angaphambili ekheshi nezitebhisi zezakhiwo eziphakeme, izitolo zezitolo, izibhedlela nezinye izindawo zomphakathi.

Qaphela: Isibonelo, lapho kukhethwa i-LFM208-4050-DR, ingcindezi yokusebenza yodlulisa ingcindezi esele ingu-50Pa. Ingcindezi yokusetha kabusha ingu-40Pa. Ngesibonisi sesikrini, ukukhishwa kwe-RS485 kokuxhumana.
Iphaneli yokudlulisa ingcindezi esele inezinkomba ezimbili: inkomba yesimo esiluhlaza kanye nenkomba ye-alamu yengcindezi;
1. Inkomba yesimo: Ngaphansi kwesimo esijwayelekile sokusebenza, ukukhanya kwenkomba okuluhlaza kuyaqhubeka; ngaphansi kwesimo sokwehluleka kwemishini, ukukhanya kokukhanya okuluhlaza;
2. Inkomba ye-alamu: Ngesikhathi sokulinganisa ingcindezi, lapho ingcindezi yomoya iphansi kunengcindezi yokusetha kabusha, ukukhanya kwe-alamu kuhlala kukhona. Uma ingcindezi yomoya iphakeme kunengcindezi yokusebenza. Ukukhanya kwe-alamu kuyakhanya. Lapho ingcindezi iphakathi kwengcindezi yokusetha kabusha nengcindezi yokusebenza, ukukhanya kwe-alamu kuyacishwa;
Uma umkhiqizo unewindi yokubonisa ingcindezi, inani lokucindezela lingaboniswa ngqo;
Yamukela into yokuzwa kwengcindezi yaseMelika
Igumbi langaphambili le-Elevator nezitebhisi zesakhiwo esiphakeme
I-basement nokuphepheka
Ukuqapha izingcindezi emahhotela, ezitolo zezitolo, ezibhedlela naso
Ezinye izindawo zomphakathi
Ukuhambisana Nezinga Likazwelonke
I-Churchnical Standard for SSquae Management System Esakhiweni Sezakhiwo
Ukuqapha ukucindezela kokuphuma komlilo. Futhi kuvimbela ukuvuza kwamagesi anobuthi nentuthu eminyene lapho kuqubuka umlilo.
